Lone Willow Island

This large wetland complex on Lake Poygan was protected by a rock breakwall many years ago. Over time, the rock breakwall subsided into the bottom sediment and waves began to overtop the structure. Hundreds of acres of marsh were eroded away as waves were able to reach the vulnerable shoreline.

To help fund the project our department secured a grant through DNR's Targeted Runoff Management program. The design called for additional rock to be placed on top of the existing rock to rebuild the breakwall above the surface of the water. The total length of the completed breakwall was 4,485 feet.
